1.)a(2b)=92b)a (2.)2x1=2 (3.) a(1/a)=1 (4.)(2s)t=2(st) (5.)4x=0=4x (6.)-2a=2a=0?

Question

state the property that is illustrated in each statement.All variables represent real numbers?

(7.) (x+y)=5=5=(x=y)
(8.) 5(-x)=5(2)=5(-x)

Answer 1

1) a(2b) = (2b)a
Commutative Property of Multiplication

2) 2x1 = 2
Identity Property of Multiplication

3) a(1/a) = 1
Inverse Property of mUltiplication

4) (2s)t = 2(st)
Associative Property of Multiplication

5) 4x + 0 = 4x
Identity Property of Addition

6) -2a + 2a = 0
Inverse Property of Multiplication

7) (x+y)+5 = x + (y+5)
Associative Property of Addition

8) You need to retype this one.
